IMPROVEMENT IN GRAlN-SEPARATORS.

pecification forming part of Letters Patent No. 125,513 dated Apiil 9,1872.

To all whom it may concern:

Be it known that I, J osnrn ALLONAS, of Mansfield, county of Richland,State of Ohio, have invented certain newand useful Improvements inGrain-Separators, of which the following is a full, clear, and exactdescription, reference being had to the accompanying drawing makingpartof this specification, in which- Figure 1 is a perspective view; Fig.2,a vertical longitudinal section; and Fig. 3, a vertical transversesection taken on the line y 3 Fig. 2.

Similar letters of reference denote corresponding parts in all thefigures.

The first part of my invention relates to making the rear end of theside board or framework which supports the tailing-spout or conveyerseparate from the main body of the machine, and connecting ittherewithby suitable fastening devices; the object of this part of the inventionbeing to make this part easily removable for transportation, for thepurpose of repairing, and to afford convenient access The manner ofattaching the screen or riddle to, and operating it directly from, theseparatingtable or the lower carrying-table. The invention furtherconsists in certain details of construction, which will be fullyexplained.

In the drawing, Ais the upper or separating table or shaker, and-B thelower table, which collects the grain as it falls through the upper oneand delivers it to the winnower or fan. These tables are of the usualconstruction, and are supported from the frame-work G O by means oflinks a b b, and are operated by cranks d d on crank-shaft D. E is thescreen or riddle, to which the grain is delivered from table B. Thisscreen is attached to table B by the metallic brackets or hanger 6, (seeFig. 1,) which also form supports for the links b e, and, in practice, Isecure the side pieces of the riddle to the bottom of the table byscrews or their equivalents. E are shaking-fingers projecting from ashaft supported in the side pieces of the riddle, and operated by anarm, 6 and a suitably-arranged stop,

' 6 as will be readily understood. F is the chute-board. Its rear end issupported upon links f, and its front end upon levers f these latterbeing pivoted to the frame-work, and connected at their upper ends totable B or riddle E by link 6 G is the fan, inclosed by the shell Gthese parts being of any ordinary construction. H is a tailingscrew, itsfunction being to deliver any imperfectly-thrashed heads or grain thatmay be overblown to the elevator I, in orderthat they shall be workedover. The trough in which this screw works, and the end pieces I, inwhich it is mounted, although they form continuations of the side piecesK of the frame of the machine, are made separate, and secured to theposts 0 by means of clamping-arms i, in order that the conveyer may bereadily detached from the other parts. The armsi may be fastened toposts 0 by nuts, keys, or similar devices. carrying the tailiu gs ;up tothe thrashing-cylinder. M is the platform of the stacker, over which thestraw is carried, by means of a raddle-belt, after it leaves theseparator. M are pulleys, over which the belt or apron runs. The lowerend of this stacker-platform is provided with a number of openings orslots, m, through which the chaff may fall as the straw passes over itwhen it is desired to effect a separation of the two. N is a hingeddoor, employed for closing openings m when circumstances make itdesirable to do so. A sliding door may be employed instead of a hingedone, when preferred.

The mass of straw and thrashed grain is delivered to the upper table A,and is moved rearward by successive impulses, the grain being deliveredthroughthe slatted bottom upon table B, and from thence to the riddlelfl. As the riddle is rigidly'attached to the table B and moves with it,there is much less racking and shaking of the machine than there iswhere the riddle moves transversely of the table but, as the tailingsare required to be delivered at one side of the machine, it is necessaryto employ the screw H. As the straw is leaving the riddle I subject itto another tossing motion by means of the rocking-fingers E.

I find it advisable to give the chute-board F, which receives the grainfrom the riddle, a counter reciprocating motion by means of lever f andlinkse as this arrangement makes the chute-board and riddlecounterbalance each other.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

FFICE.

I is the elevator for v 1.. The combination of the reciprocating table Band riddle 1*], when connected and supported b 'hangers c, constructedas described.

2. In combination with riddle E, connected to and reciprocating in aright line with the table B, the oscillating fin gers E, operated bymeans of stop a, substantially as set forth.

3. In combination with the riddle E, attached to and operated by thetable 13, the counter-reciprocating chute-board F, connected with andoperated from table B by means of lever f and links 0 b.

4. The side pieces I, supporting the tailingspout or trough, when madeseparate and detachable from the side pieces K of the main frame, andconnected to the same by bolts, hooks, or othersuitable attachingdevices, substantially as and for the purpose set forth.
